Secondary Cell Activation Using Temporary Reference Signals and Beam Selection

3. The UE of claim 2, wherein the one or more processors are further configured, individually or in any combination, to cause the UE to receive a media access control control element (MAC-CE) indicating the at least one of the QCL information or the TCI state for the first reference signal.

4. The UE of claim 2, wherein the one or more processors are further configured, individually or in any combination, to cause the UE to receive a downlink control information (DCI) indicating the at least one of the QCL information or the TCI state for the first reference signal.

5. The UE of claim 2, wherein the one or more processors are further configured, individually or in any combination, to cause the UE to receive downlink data comprising the activation command, and wherein the downlink data indicates the at least one of the QCL information or the TCI state for the first reference signal.

12. The UE of claim 9, wherein the first subset comprises consecutive reference signal bursts.

13. The UE of claim 9, wherein the first subset comprises non-consecutive reference signal bursts.

15. The UE of claim 1, wherein the plurality of reference signal bursts comprises a plurality of tracking reference signals (TRSs).

16. The UE of claim 1, wherein the first reference signal comprises a non-zero power (NZP) channel state information reference signal (CSI-RS).

17. The UE of claim 1, wherein the first reference signal comprises a tracking reference signal (TRS).

20. The method of claim 19, wherein the receiving the beam information comprises receiving a media access control control element (MAC-CE) indicating the at least one of the QCL information or the TCI state for the first reference signal.

21. The method of claim 19, wherein the receiving the beam information comprises receiving a downlink control information (DCI) indicating the at least one of the QCL information or the TCI state for the first reference signal.

22. The method of claim 19, wherein the receiving the activation command comprises receiving downlink data comprising the activation command, and wherein the downlink data indicates the at least one of the QCL information or the TCI state for the first reference signal.

27. The method of claim 18, wherein the first reference signal comprises a non-zero power (NZP) channel state information reference signal (CSI-RS).

28. The method of claim 18, wherein the first reference signal comprises a tracking reference signal (TRS).
